Hello All, I am facing issues under openstack rocky with last libvirt available on centos 7.
There is an open discussione here:

About sending garp when an instance live migrate. 
What must send garp ?

The problem is this: when live migrate a vm from a node to another it stops to responds to ping requests. It starts to respond only when it send a network request for example when its chrony daemon pools a server.
Anyone could help me, please?
Best Regards 
Ignazio
